Score Breakdown
Scored for Aggressive Growth profile
Sub-scores are 0–20 each; Model Score is weighted by your selected investment goal. How it works →
Why Ranked Here
- The composite score of 54.1/100 is anchored by a perfect profitability sub-score of 20.0/20, which alone contributes the maximum possible points from that dimension and confirms Arista as a fundamentally strong operator within the Technology / Computer Hardware sector.
- The growth sub-score of 17.5/20 adds substantial positive weight, reflecting that revenue, net income, and EPS growth as measured in the FY2025 10-K filing are well above average for the model's scoring universe.
- The momentum sub-score of 13.0/20 provides additional support, indicating that the quarterly cadence within the filing year showed measurable operational improvement rather than stagnation.
Why Not Higher
- The dividend sub-score of 0.0/20 and theme sub-score of 0.0/20 together remove 40 potential composite points from the model output — Arista pays no dividend and was mapped to zero macro themes in this scoring cycle, creating a structural ceiling on the aggregate score regardless of operational quality.
- The financial health sub-score of 8.0/20 prevents the fundamental portion of the model from reaching its maximum potential, indicating that leverage or balance sheet metrics from the 10-K filing are not yet at the level that would support a top-tier health score.

Arista Networks, Inc. is a U.S.-based technology company specializing in cloud networking solutions, primarily designing and selling high-performance Ethernet switches, routers, and network management software for large data centers, cloud service providers, and enterprise networks. Its EOS (Extensible Operating System) platform differentiates it from legacy networking vendors by offering a programmable, software-defined architecture. The company's model score of 54.1/100 reflects a genuinely bifurcated picture: outstanding profitability and solid growth offset by a complete absence of dividend income contribution and zero scored macro-theme exposure, which together suppress the composite score significantly. The profitability sub-score of 20.0/20 — a perfect reading — indicates that Arista's net margins, operating margins, and return on assets as reported in its FY2025 10-K filing are among the strongest the model can capture, while the growth sub-score of 17.5/20 confirms robust year-over-year expansion in revenue, net income, and earnings per share. However, the dividend sub-score of 0.0 and theme sub-score of 0.0 together remove 40 potential points from the composite, pulling an operationally elite company to a mid-range aggregate score. The key research tradeoff is therefore straightforward: Arista presents as a high-quality, cash-generative business with strong operational momentum, but researchers focused purely on the composite model score should understand that the score discounts are mechanical rather than indicative of fundamental weakness — the company simply retains earnings rather than distributing them and was not mapped to macro themes in this filing cycle.
Plain English
Arista Networks builds the high-speed networking equipment that powers modern cloud data centers — think of it as the company that makes the 'plumbing' that allows Amazon, Microsoft, and Meta to move enormous amounts of data at very high speeds. The model score of 54.1/100 doesn't mean the company is mediocre; it means the scoring model docks points because Arista pays no dividend and wasn't tagged to macro themes, even though its profitability and growth scores are near-perfect. The Medium risk rating reflects the fact that Arista's business is concentrated among a small number of very large cloud customers, so while the fundamentals are strong, the research profile carries concentration and cyclicality considerations. For an aggressive growth researcher, this company scores 70.2 against that specific goal profile — one of its stronger alignments in the model.
Bull Case vs. Bear Case
Bull Case
- Arista's profitability sub-score of 20.0/20 — a perfect score — signals that the company's net margin, operating margin, and return on assets as reported in its FY2025 10-K are at the top of the model's measurable range, demonstrating sustained pricing power and operational efficiency.
- The growth sub-score of 17.5/20 reflects strong year-over-year expansion in revenue, net income, and EPS from the regulatory filing, suggesting that demand for Arista's cloud networking solutions continues to compound meaningfully at scale.
- The momentum sub-score of 13.0/20 indicates sequential quarterly improvement in revenue, earnings, or margins within the FY2025 filing period, pointing to an accelerating rather than decelerating operational trajectory.
Bear Case
- The financial health sub-score of 8.0/20 is notably the weakest fundamental sub-score in the model output, suggesting that leverage ratios, interest coverage, or balance sheet composition as reported in the 10-K present relative concerns compared to the company's otherwise strong operational profile.
- Arista's revenue base is heavily concentrated among a small number of hyperscale cloud customers, meaning any reduction in capital expenditure by those key accounts could disproportionately impact revenue and earnings growth as captured in future filings.
- The momentum sub-score of 13.0/20, while positive, leaves meaningful room for improvement and does not yet confirm the kind of consistent acceleration that would push the composite score into higher-conviction territory under the current model version.
What Could Change the Picture
Bullish Triggers
- Evidence in future 10-K filings of a materially improved financial health sub-score — through debt reduction, stronger interest coverage, or a more conservative balance sheet posture — would remove the one fundamental weak point and lift the composite score.
- Initiation of a share repurchase program that generates measurable EPS acceleration, combined with continued double-digit revenue growth, would push both the growth and momentum sub-scores closer to their ceilings and strengthen the overall research profile.
Bearish Triggers
- A deceleration in the growth sub-score in a subsequent 10-K filing — particularly if revenue or net income growth rates compress significantly — would undermine the primary bull case and signal that hyperscale customer spending cycles are turning negative for Arista.
- Any deterioration in the profitability sub-score away from its current perfect 20.0/20 reading, potentially caused by pricing pressure from competitors or rising cost structures, would represent a meaningful negative signal given that profitability is the company's strongest differentiating factor in this model.
Red Flags
- The financial health sub-score of 8.0/20 is the only sub-score that falls into the lower half of the 0–20 range, warranting closer review of the leverage and balance sheet disclosures in the FY2025 10-K filing to understand whether debt levels or interest obligations have shifted materially.
Risk Profile
Medium RiskThe Medium risk rating reflects Arista's dependence on a concentrated set of large hyperscale cloud customers for a substantial portion of its revenue, meaning that while the company's financials as reported in its 10-K are operationally excellent, the business model carries inherent cyclicality tied to the capital expenditure decisions of a small number of counterparties. The financial health sub-score of 8.0/20 also introduces some balance sheet uncertainty that, combined with customer concentration, places the risk profile above the low-risk threshold.
Key Catalysts to Watch
The key factors to monitor for Arista's research profile are the trajectory of hyperscale data center capital expenditure disclosures from its largest customers and any quarterly earnings trends that would shift the momentum sub-score upward from its current 13.0/20 toward the top of the range. Additionally, any announcements or filing disclosures related to balance sheet changes — particularly debt levels or cash deployment strategy — would directly affect the financial health sub-score, which is currently the most significant fundamental constraint on the composite model score.
